Shaping networks and limiters for educational laboratory purposes
Barč, Andrej ; Domanský, Ondřej (referee) ; Šotner, Roman (advisor)
This bachelor thesis deals with design and implementation of shaping diode circuits and double - sided diode limiter of sinusoidal signal for laboratory use in low frequency band. This is a 3-segments and 6-segments shaping circuit with and without active element (without operational amplifier). The circuits form a triangular signal to harmonic signal. The aim of the design was to achieve the least possible distortion of the output signal on the largest frequency range of usability. The functionality of the circuits was verified by measurement and a laboratory protocol was constructed from the measurement result. The measurement results were compared with the results of ideal simulated waveforms.

Fully analog aquarium for growing tropical plants
Domanský, Ondřej ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
The aim of the thesis will be to clarify issues relating to the cultivation of tropical plants in aquariums. The main aspect of the work is to analyze the ideal environment for the home aquarium and the choice of specific components for plant growth. In the next sections will illustrate also the proposal of such a system and its implementation in ambient conditions.

Analogue comparators for educational laboratory purposes
Šafařík, Daniel ; Petržela, Jiří (referee) ; Domanský, Ondřej (advisor)
The goal of this bachelor thesis is to design complete solution for assembling of laboratory task on comparators topic. This thesis contains an introduction on comparators and a subsequent analysis of some of their basic functions. Thesis also contains design and simulation of the individual parts in the OrCAD program, from which the final product for laboratory task is constructed. There is also design of the printed circuit board along with its measurements. Another part is the process of designing and verifying its functionality. A sample protocol is prepared for the laboratory task.

Synthesis of circuit element with fractal dynamics
Domanský, Ondřej ; Hruboš, Zdeněk (referee) ; Petržela, Jiří (advisor)
The first aim of this diploma thesis is to clarify problems with circuit elements described by the fractional-order dynamics, show their basic properties and possible applications in circuits with lumped parameters. The second topic is covering the synthesis of two-terminal devices which have different fractional-orders for requested phase shifts. For this kind of devices, the thesis also describes their optimization and approximation in the frequency domain and subsequent implementation in the form of passive ladder structures. The final part of diploma work will be focused on practical realization of universal fractional PID controller and the verification of proper function of this multi-port in various configurations to prove its correct function via real measurement of frequency and time responses.
